Two-part allegorical saying related to physics

I also spent a lot of time. I looked up several materials and summarized them here. The quantity should be enough.

first part

1, mercury falls to the ground-everywhere (the density of mercury is greater than the density of substances that make up the ground, and mercury is mobile, so it will always be 2, sinking under other substances). Loach makes friends-oily to oily (the surface of loach is smooth and smooth, with little friction. )

3, the egg hits the stone-finished (the pressure on the eggshell is far less than the pressure that the stone can bear. When an egg hits a stone, it breaks first. )

4, ponytail tied with tofu ~ I can't lift it (the pressure of tofu is very small. When the ponytail is tied to tofu, the contact area with tofu is very small. When you lift tofu, the gravity of the tofu block is pressure, which is greater than the pressure on tofu, so you can't lift it, you can only cut it off. ) 5. Ship leakage-there is pressure in the liquid. After the ship is broken, the water outside the ship is forced to enter the ship until the night of 1. The water surface is even, so the water in the boat won't flow out at this time.

6, water hyacinth-can't sink (the density of water hyacinth is less than, so it can only float on the water)

7. Sit and look at the sky-what you see is very small (the principle of straight-line propagation of light)

8. photographic negative-reverse black and white (the camera is made by applying the principle of putting the object out of the focal length of the convex lens twice, and it is reversed and reduced, so the image on the photographic negative is reversed from the person. The negative is coated with a photosensitive agent. When people take pictures, the reflected light enters the black box of the camera and reacts with the photosensitive agent on the negative film. Because the photosensitive agent has strong reflection ability to light and the dark part has strong absorption ability to light, only a little reflected light is emitted to the negative film. In this way, the light-colored parts have strong photosensitivity on the film, and the dark parts have weak photosensitivity. When the film is developed, the photosensitive part is basically washed away, so it is light, and the photosensitive part is dark because it can't be washed away by photochemical reaction. )

the second part

1. Pig Bajie looks in the mirror, but it's not human inside and outside-according to the imaging law of flat mirror, the images formed by flat mirror are equal in size and the objects are symmetrical, so what Pig Bajie sees is "exactly the same" as himself, or the image of a pig, and naturally it's not human inside and outside.

2. Fire and water are incompatible-when a substance burns, it must reach the ignition point. Because of the large specific heat of water, water can absorb a lot of heat when it comes into contact with fire, which will reduce the temperature of the ignited object; At the same time, the vaporized water vapor surrounds the burning object, making it impossible for the object to contact with air. Without air, combustion cannot be carried out.

According to Einstein's theory of relativity, sailing in a spaceship near the speed of light will lead to the passage of time much slower than on earth. If you live in this "cave" for a few days, you have spent years, decades, even hundreds and thousands of years on the earth.

4. clairvoyance, clairvoyance-people use electromagnetic waves to transmit sound and image signals, making the ancient myth of "clairvoyance, clairvoyance" come true. And human vision has far exceeded "thousands of miles".

5. Sitting on the ground, walking 80,000 miles a day-because the radius of the earth is 6,370 kilometers, the distance that objects on its surface "walk" is about 40,003.6 kilometers, about 80,000 miles. Scientifically reveals the relationship between motion and stillness-motion is absolute and stillness is always relative to the reference object.

6. Stop at the bottom-there are two conditions for liquid boiling: one is to reach the boiling point, and the other is to continue to absorb heat. When the salary is paid, the boiling of the liquid can stop.

7. Flowers in the wall are fragrant outside the wall-because of irregular movement, flowers in the wall will spread outside the wall.

8. Looking at the sky from the well, you can see very little-because light travels along a straight line, from the knowledge of geometric drawing, the frog's field of vision will be very small.

9. fidgeting-according to the pressure formula, when the pressure is constant, the smaller the stress area, the greater the pressure. People will feel very uncomfortable sitting on such a blanket.

10. Xue Rui shines brilliantly in a good year-there are many loose gaps in the snow falling to the ground, which is filled with stagnant air, which is a bad conductor of heat. When it is covered on crops, it can well prevent heat conduction and air convection, so it can play a role in heat preservation.

1 1. Don't go out in the morning, but take Wan Li Road at night-a bright red sunrise appears in the morning, indicating that there are many water drops in the atmosphere, which indicates that it will turn rainy. If there is a fiery red or golden sunset, it means that there is no cloud in the west and the sun can only transmit, indicating that the weather will clear up.

12. Weigh it slightly-according to the principle of lever balance, if the power arm is a fraction of the resistance arm, then the power is several times the resistance. If the load-bearing arm is large, it is entirely possible to "dial one or two kilograms."

13. Broken mirrors cannot be reassembled-when the distance between molecules is large (more than several hundred angstroms), the attraction between molecules is very small, almost zero, so it is difficult to reassemble broken mirrors.

14. If the components are in the same direction, the resultant force is equal to the sum of the components.

15. Tofu can't be lifted with hemp rope-when the pressure is constant, the stress area is small and the pressure is high.

16. Real gold is not afraid of fire, and truth is not afraid of argument-from the melting point of gold, although it is not the highest, it also has 1068℃, while the temperature of general flame is about 800℃. Because the temperature of the flame is lower than the melting point of gold, gold cannot be melted.

17. The moon is dizzy and windy-when the wind comes, the temperature in the upper air drops rapidly, and the water vapor condenses into small water droplets, which is equivalent to many prisms. Moonlight is scattered through these prisms, forming a colorful halo, so there is a saying that "the halo is windy."

18. It rains on a wet basis-that is, the ground is against the tide. Before the rainstorm, the air humidity is high, the ground temperature is low, and the water vapor near the ground condenses into small water droplets. In addition, the salt contained in the ground is easy to absorb wet water vapor, so the ground against the tide indicates shanghai dawn.

19. With a long whistle, the sound of the mountain echoes the valley-people whistle in the mountain, and the sound can form a loud echo after repeated reflection, which will last for a long time, as if the mountain is shouting and the valley is echoing.

20. But you can't hear the sound-in the process of wave propagation, when the size of the obstacle is smaller than the wavelength, obvious diffraction will occur. The height of the fence is several meters, and the wavelength of sound wave is larger than the height of the fence, which can bypass the high wall and let people outside the wall hear it; Light waves are smaller than the size of a high wall in the long run, so light can't be diffracted outside the wall, and people outside the wall can't see people inside.

2 1. Boiling water doesn't ring, ringing water doesn't open-before the water boils, most bubbles burst under the pressure of water, and the cracking sound and vibration sound are accompanied by the container ringing, so the sound is very loud. Water will be isothermal up and down after boiling, so this phenomenon will not occur. .

22. One day in the cave, the world has passed thousands of years-according to Einstein's theory of relativity, sailing in a spaceship near the speed of light, the passage of time will be much slower than on the earth. Living in this "cave" for a few days, the earth has spent several years, decades, even hundreds and thousands of years.

23. clairvoyance, clairvoyance-people use electromagnetic waves to transmit sound and image signals, making the ancient myth of "clairvoyance, clairvoyance" come true. And human vision has far exceeded "thousands of miles".

24. Flowers in the wall are fragrant outside the wall-because of irregular movement, flowers in the wall will spread outside the wall.

25. Looking at the sky from the well, you can see very little-because light travels in a straight line, from the knowledge of geometric drawing, the frog's field of vision will be very small.

26. Cold before frost, cold after snow-in late autumn night, the temperature near the ground suddenly turns cold (below 0℃), and the water vapor in the air condenses into small ice crystals, which attach to the ground to form frost, that is, it feels "cold before frost". When snow melts, it needs to absorb heat to reduce the temperature of the air, that is, it feels "cold after snow"

27. Until I raised my cup, I asked the bright moon to bring me my shadow, so that the three of us-one of the three "people" here is formed by the straight-line propagation of light.

28. A drop of water can see the sun, and one thing can see the spirit-a drop of water is equivalent to a convex lens. According to the law of convex lens imaging, the image of the sun can be seen through a drop of water, and the small one can see the big one.

29. If an egg hits a stone, it will bite off more than it can chew. Although the force is the same, every object can bear a certain pressure. If this limit is exceeded, the object may be damaged. Eggs can withstand less pressure, so they will break. You can't wrap the fire in paper-paper will burn when it reaches the ignition point. 3 1. It has the natural fragrance of musk deer, so why do you want to lift it against the wind-the phenomenon of gas diffusion?

332. Jade is uncut and abrasive-jade is uncut and unpolished, with uneven surface and diffuse light. After the jade is polished, its surface will be smooth and the light will be mirror-like.

33. The fan has a cool breeze, so summer is better than winter-when the fan is used in summer, the air flow is accelerated, which makes the sweat on the human surface evaporate faster, and people feel cool because of evaporation and heat absorption.

34. Man struggles upwards and water flows downwards-it is an objective law of nature that water flows downwards, because it is influenced by gravity.

35. The water tank perspires, without load-due to evaporation, the temperature below the water surface is lower than the air temperature, and the water vapor in the air liquefies at low temperature, and the water droplets adhere to the outside of the water tank. There is a lot of water vapor in the air, so there is a great possibility of rain. Of course, there is no need to water the land.

36. Snow won't make it cold-snow is formed by condensation of water vapor or water droplets in the sky. Coagulation and solidification are exothermic processes, and snow melting is a melting process, which requires heat absorption.

37. When snow falls in the mountains, frost the plains first-the temperature in the mountains is lower than that in the plains below, so the snow falling on the mountains is not easy to melt, and the snow falling on the plains is easy to melt in time, so the same snow falls on the mountains, more than on the plains. Frost is the result of condensation of water vapor on the ground. There is more water vapor on the surface of the flat land under the mountain than on the mountain, so the flat land is easy to mix with frost, but it is not easy to frost on the mountain.

38. Rome wasn't built in a day-water and ice are poor heat conductors, and smooth and bright ice can prevent radiation. Therefore, the three heat transfer methods are not easy. The water under the ice releases heat very slowly, forming thick ice, which naturally takes a long time to cool down.

39. There will be wind next to the fire-the air near the fire is heated and expanded, and the cold air in the distance is poured in, and the flow of hot and cold air forms wind.

40. a stone breaks the sky-the calm water surface is like a flat mirror, and you can see the image of the sky. A stone was thrown into the water, destroying the calm water surface, forming layers of water waves and diffuse reflection, and the image of the sky in the water was "broken".

4 1. Blind people light candles-people can see everything in the world because sunlight or light used for lighting shines on objects and is reflected by them, so the reflected light can't enter the eyes of the blind people, so the blind people can't see objects.

42. Raindrops in the early rainbow, rain clouds in the late rainbow bask in the face-rain clouds in China move from west to east. The rainbow seen in the morning is a western rainbow formed by sunlight from the east shining on water droplets in the rain layer in the western sky. Obviously, the rainbow in the west indicates that it will rain locally. On the contrary, the rainbow seen in the evening is the rainbow in the east, which indicates that there are no rain clouds in the western sky and the weather is bound to be sunny. 44. Photographic negative-reverse black and white-the camera is reversed to reduce the real image, so the image on the negative is reversed from the person; When people take pictures, because the bright (dark) part has strong (weak) reflective ability, more (less) will enter the black box of the camera, so the bright (dark) part has strong (weak) sensitivity on the film, and the film is developed, and the strong (weak) sensitivity part is dark (light).

45. Sharpening the knife does not mistake the woodcutter-reducing the compressed area and increasing the pressure.

46. It takes one hand to shoot-force is the action of one object on another, and one hand can only shoot the other hand or other objects to produce the action of force and make a sound.

47. 421,000 pounds-the balance condition of the lever, increase the ratio of the power arm to the resistance arm, and use only a small force to pry up a heavy object.

48. Mercury falls to the ground-everywhere-the density of mercury is greater than that of the substances that make up the ground, and mercury is mobile, so it always sinks under other substances.

49. Loach makes friends-smooth to smooth-the surface of loach is smooth and lubricated with little friction.

50. The ship is leaking-there is pressure in the liquid. After the ship is broken, the water outside the ship is forced into the ship until the water surface inside and outside the ship is even. At this time, the water in the boat will not flow out.

5 1. The gourd on the water can't sink-the density of the gourd is less than that of water, so it can only float on the water.

52. A rope saws wood, but a drop of water wears it through. -Because the rope is in contact with the wood block, when the water is in contact with the stone, the stress surface is very small, resulting in great pressure, so the rope can cut off the wood block and the water can drip down through the stone.

53. There are some plums in the corner. Ling cold opens them alone. I knew from a distance that it wasn't snow, because there was a smell coming. Molecules in an object are moving irregularly. This is the diffusion phenomenon of gas molecules.

If an apple leaves a tree, it won't fall far. -Because the direction of gravity is vertical downward, the apple won't fall far away from the tree.

55. Climb high and fall hard-because all lifted objects have gravitational potential energy, the higher the lift, the greater the gravitational potential energy, so climb high and fall hard.

When the ship broke down in the middle of the river, it was too late to pull back from the cliff. All objects have inertia, that is, the property of keeping the original state of motion unchanged. So it is difficult for the boat to stop in the middle of the river.

57. Small bamboo rafts are in the middle reaches of the river and walk on both sides of the towering green hills. -Relativity of object motion, whether the object is moving or stationary depends on the selected reference object.

58. The tank wears a skirt and it rains heavily. -Why do cylinders wear skirts? Because the water vapor in the air will liquefy when it is cold, small water droplets will be formed and attached to the outer surface of the cylinder. At the same time, it also implies that the temperature is dropping and heavy rain is coming.

59. Wear leather clothes early, wear gauze at noon and eat watermelon with the stove. -The specific heat capacity of sand and gravel is smaller than that of water.

60. Jade is uncut and abrasive-jade is uncut and unpolished, with uneven surface and diffuse light. After the jade is polished, its surface will be smooth and the light will be mirror-like.

6 1. What you can't catch is the moon in the water, but what you can't pick is the flower in the mirror. Because objects are like water and virtual images in the mirror, you can't catch the moon in the water or pick flowers in the mirror.

62. One leaf blocks the eye, but Mount Tai is not seen. -Light travels in a straight line in the same homogeneous medium.

15. The face of the peach blossom is red-the peach blossom reflects red light.

63. Major earthquakes are dull, while minor earthquakes are sharp. -this is because the vibration frequency of the earthquake is small, so the tone is low and the sound is heavy; Small earthquakes have high vibration frequency, so they have high pitch and sharp sound.

64. The echo lasted for three days. -sound will reflect back when it meets an object, that is, echo.

65. Swallows fly low with rain-before it rains, the air humidity is very high, and the wings of small flying insects are wet and they can't fly high. Swallows also fly low in search of food.

Looking for the moon in the water is empty-you can see the moon in the sky and the "moon" in the water on a moonlit night. The water surface is equivalent to a flat mirror. According to the imaging characteristics of flat mirror, the "moon" in water is actually a virtual image of the moon in water, which is of course out of reach.

67. The higher the frequency, the higher the tone of the sound. Of course, fewer people can sing along.

68. Ants climb high, and it will rain soon; It's windy around the moon-every time the weather gets worse, the water vapor in the air will increase and the air pressure will decrease. Too much steam makes the soil wet again, so the ant nest is particularly wet. As the air pressure drops and the dirty gas accumulated in the soil escapes, it is difficult for ants to live in their nests, so they have to move busily.

69. Spiders add silk and the sky clears up-spiders make a living by weaving webs to catch small flying insects and are particularly sensitive to air humidity. On cloudy days, the air is wet and heavy, and spiders are wet and sticky, so it is difficult to catch bugs. As the weather improved, the air humidity gradually decreased, and spiders began to stir, busy adding silk webs and catching small flying insects. 43. The rainbow is high and the sun is low. You wear hemp fiber in the morning and evening. When the sun is low, the sun is close to the horizon, and the heart of the rainbow is close to the horizon. You can see half the arc of the rainbow on the ground. If there are a lot of water droplets in the air at this time, the distribution space is wide, and neon can be seen in addition to rainbow. The semi-arc of the neon ceiling is higher than the rainbow and close to the zenith, which indicates that the rain clouds have moved close to the zenith and there will be heavy rain soon.
